Click the gearwheel on the upper right side to set your aspect ratio and your default network to stream with.

When you have configured these settings, click the gearwheel again to collapse this menu.

Below the stream name is a small Twitter bird icon. By default, it is blue, indicating that the stream to Periscope will also be tweeted to the Twitter account connected to your Periscope account. If you do not want your stream on Twitter, click the bird icon to disable it.

Clicking the gearwheel in the popup menu will allow you to choose which of your available network connections you will send your stream though (this example only has one).

Below this, you can specify a network to use if you wish to stream using a network different from your default set network. This is handy if you intend to add other providers and wish to use different connection types for each stream.

When you are ready to start streaming, click Go Live in the bottom right corner.

When your event is over, click the red Streaming button to end the stream.

When you stream ends, you can see information about your viewers and for how long you streamed. Choose to either save your video on demand or delete it.
